Java的序列化，ObjectInputStream的，非阻塞I / O [英] Java Serializable, ObjectInputstream, Non-blocking I/O

问题描述

我刚刚开始接触Java序列化，我不是你应该如何从一个源对象的情况下与非阻塞I / O清楚了。

I'm just starting out with Java serialization, and I'm not clear on how you are supposed to get objects from a source in a scenario with non-blocking I/O .

所有我能找到的文档建议使用ObjectInputStream的是正确的方式序列化对象读取。但是，正如我所说，我使用的java.nio和执行非阻塞操作。如果调用readObject（）将阻塞，直到一个新的对象是可用的，这并不能帮助我

All the documentation I can find suggests using ObjectInputStream is the proper way to read in serialized objects. However, as I mentioned I'm using java.nio and performing non-blocking operations. If readObject() will block until a new object is available, this can't help me

推荐答案

在总结报告的有效载荷长度的协议序列化实例，和有效载荷是有问题的实例。然后，一旦你知道你有重新presents一个完整的实例，你可以使用ObjectInputStream的安全知道它不会阻止段。

Wrap the serialized instances in a protocol that reports a payload length, and the payload is the instance in question. Then once you know you have a segment that represents a complete instance you can use ObjectInputStream safely knowing it won't block.

协议这样的
前32位：有效载荷长度
有效载荷长度位：序列数据

Protocol like this First 32 bits: Payload length Payload length bits: Serialized data

有时我惊奇甚至自己。
